This invention relates to recessed type sash for mounting a pane ofglass in commercial and residential windows.

One object of the invention is to provide a metal sash which may berecessed into the sidewalls and ceiling of window openings whereby largepanes of glass may be readily and accurately mounted or demounted.

Another object of the invention is to provide a substantially weathertight sash having sufiicient resiliency to prevent destructive pressuresbeing imposed upon the glass as a result of temperature changes,displacement or sag in the building structure, and sudden variations inwind pressure upon either side of the glass.

A further object of the invention is to provide an improved form ofrecessed metal sash in which the face or closure member is resilientlyheld in place without the possibility of setting up stressconcentrations on the glass pane through commercial tolerances in thesize of the sash or pane of glass.

A still further object of the invention is to provide a single metalrecessed type sash which will permit the mounting of a plurality ofthicknesses of glass therein.

Recessed type sash for mounting panes of glass are old. Many examples ofthis type of sash have been found in residential as well as in largeglass openings for commercial establishments. In a broad sense all sash,particularly metal sash, are in part recessed into the wall and ceilingstructure of the window opening. One early form of metal sash of thistype is shown in Murnane Patent 1,008,984 of November 14th, 1911 andToney Patent 1,994,464 of March I9, 1935. Later improvements in metalsash in which the channel or gutter member may be mounted substantiallywholly within the plane of the wall or ceiling and the face or closuremember inserted parallel with the glass are shown in Reuter Patent1,589,560 of June 22, 1926, Peterson Patent 2,185,735 of June 2, 1940and Ketchum Patent 2,463,284 of March 1, 1949.

All of the foregoing types of metal sash have one or more commonconstruction characteristics which make them unsuitable when adapted toa metal sash in which the gutter member is substantially wholly recessedwithin the plane of the Wall and ceiling window openings. The Murnane,Peterson and Ketchum type of sash are excellent in regard toadjustability for different thicknesses of glass, but in order to securethe glass in position they grip the glass adjacent its margins betweenrelatively heavy and rigid metal sections of the sash. Furthermore,these types of sash tend to create unequal stress concentration at eachadjustable member due to the inability of the ordinary workman to applythe same tension on each adjusting member screw throughout the length ofeach face member.

All of the foregoing disadvantages are avoided in the hereinafterdescribed invention in which Fig. 1 shows a portion of a store frontwith the sash and glass in position; Fig. 2 shows in enlarged detail atypical section on the lines 2-2 through the glass and sash of Fig. 1;Fig.

3 shows in perspective one form of the resilient and adjustable faceclip of the invention; Fig. 4 shows in assembled relation the guttermember, face member and resilient face clip of a modified form of theinvention. Both Figs. 2 and 4 show in dotted lines the compensatingfeature of the resilient face clip therein to compensate for commercialvariations in both the metal sash and glass thickness.

Referring now to Figs. 1 and 2 of the drawings reference character 1indicates a building structure having a window opening therein closed bythe glass 2. Within the building structure at each side of and above thewindow opening is a suitably shaped channel opening 111 to receive therecessed sash comprised of a gutter member 3 and face member 4. Thegutter member is recessed substantially iiush with the plane of theadjacent build ing wall and ceiling. At the bottom of the window the useof a recessed sash is possible but a sash having a fully exposed faceplate is preferred for ease of mounting and replacing the glass 2. Hencethe sash 5 at the base of the window is preferably one in which the facemember 6 is inserted in a direction normal to the glass as in my Patent1,994,464 hereinbefore referred to.

One form of the sash structure of the invention is best shown in Figs. 2and 3 of the drawings wherein the gutter member 3 comprises a bottomwall 7 terminating in side walls 8 and 9 extending towards the Windowopening. The side wall 8, inwardly of the glass, terminates in a flange1t directed towards the glass and. preferably provided with an inwardlyturned flange 11. This flange 11 serves as a support againstwhich theglass is placed when mounting the glass within the sash. The oppositegutter member side wall 9, outwardly of the glass, preferably terminateswithin the plane of the adjacent wall or ceiling. Mounted in the bottomwall 7 of the gutter member are suitable face member clip mounting meanssuch as the bolts 12. The bolts 12 may be secured to the gutter bottomwall 7 in any desired manner, preferabl by recessing the bottom wall 7,as at 13, so that the bolt head lies within the plane of the outer faceof the wall 7. The gutter member 3 is mounted in the wall or ceilingwithin the channel shaped opening 15. thereof by any suitable means suchas the screws 1-6 in the apertures 15 of gutter bottom wall 7.

The face member clips 16 are generally of Ushape and are disposed inlongitudinally spaced relation within the gutter member 3. These clipsare preferably of resilient material for a purpose hereinafterdisclosed. Each clip 16 includes a web 17 terminating at one end in adepending portion 18 to which is joined the outwardly directed arm 19.The opposite end of Web 17 terminates in an outwardly directed arm 20.Arm 19 adjacent its free end has an offset comprised of the portions 21and 22 which preferably lie wholly within gutter 3. The arm 20 has itsfree end 23 deflected towards the arm 19. These clips are secured Withinthe gutter 3 by the bolts 12 which pass through aperture 24 in the Web17 of each clip. This web 17 bears against the longitudinally extendingand spaced gutter bottom wall extensions 25 and 25a to provide a bearingfor the nut 26 of the bolt 12. As best illustrated in Fig. 3 of thedrawings, aperture 24 in web 17 is elongated so that clip 16 may beshifted laterally. The lateral tongues 27 and 28 struck from the web 17selectively engage the gutter bottom wall extension 25a to position theclip 16 upon bolt 12 and accommodate different thickness of glass 2. Themost popular glass thicknesses being A and /8 inch.

The face member 4 of the sash of Fig. 2 comprises a Web 29 extendingoutwardly from glass 2 for closing the opening of the gutter member 3.The web has two inwardly extending portions 30 and 31 which co-operate"gutter members 3 and with face lug 16 to resiliently retain the facemember in position. The web 29 of the face member preferably overlapsthe adjacent wall or ceiling surface 1. Adjacent the glass 2 andintegrally formed upon the inner face of web 29 is an inwardly extendingflange 30 which is preferably directed towards the glass so as to forman acute angle with the inner face of the web 29. Adjacent the arm 9 ofthe gutter member and integral with the inner face of web 29 is aninwardly extending flange 31 having an offset portion 32 directedtowards gutter arm 9 for engagement with the offset portion 21 of faceclip arm 19. Upon reference to Fig. 2 it will be apparent that the facemember web 29, when the sash is assembled, rests upon face clip portion23 and upon the adjacent wall or ceiling surface 1.

A modified form of sash is illustrated in Fig. 4, wherein gutter member103 comprises a bottom wall 107 having outwardly extending arms 108 and109. Arm 108 terminates in a flange 110 directed towards glass 2 and areentrant flange 111 for normally engaging the glass. Arm 109 of thegutter member has, intermediate its ends, an inwardly offset portion109a for engagement with face clip 116. Intermediate the arms 108 and109 of the gutter member and upon the inner face of bottom wall 107 isan inwardly projecting lug 107a which also engages the face clip 116.

The face member 104 of Fig. 4, is substantially the same as the facemember 4 of Fig. 2 and includes web 129 with the inwardly extendingportions 130, 131 and 132. The face clip 116 of Fig. 4 is a modifiedform of the face clip 16 of Fig. 2. Here the face clip 116 includessimilar arm 120 with its portion 123 and similar arm 119 with itsportions 121, 122. The arcuate web 117 of the modified face clip hassuitably formed portions 117a and 11712 which engage with the guttermember portions 109a and 107a to retain the clip in position within thegutter member. This face clip 116 is also made of resilient material andthe arcuate shape of web 117 readily permits deflection thereof so thatthe clip may be snapped into place between gutter member portion 109aand 107a.

The resilient face clip 16 of Fig. 2 and 116 of Fig. 4 normally have thearms and 120 spread a greater distance relative to the opposite arms 19and 119 respectively as indicated by dotted lines. The purpose of thisis to normally cause a slight deflection of these arms 20 and 120 whenengaged with the glass 2 so that the clip snugly but resiliently retainsthe glass against the adjacent flange 11 and 111 respectively of thegutter member.

The manner in which the sash of Figs. 2 and 3 are mounted within thebuilding structure and assembled with the glass will now be described.At the ceiling and wall or walls of the window opening a suitablesubstantially channel shaped opening is formed in the adjacent buildingstructure for the full size of the window opening. Within these channelshaped openings are mounted the gutter members 3 and are secured inposition by any suitable means such as the screws 14. At the bottom ofthe Window opening is mounted an L-shaped gutter member of the generaltype described and claimed in my patents, No. 2,475,682 of 1949 and No.1,994,464 of 1935.

The glass 2 is then picked up in the usual manner as by canvas straps orsuction cups and while the top edge is inclined inwardly, one side edgeis diagonally moved into the gutter members of a wall and ceiling of thewindow opening. By this time the bottom edge of the glass is slightlyabove the bottom wall of the bottom gutter member such as 27 of myPatent 2,475,682 and indicated as 27A at the bottom of Fig. 1 of thepresent drawings. The glass, at one side edge, has now movedsufliciently far into the gutter member 3 of one wall of the Windowopening so that the opposite side edge of the glass may be rotatedinwardly and aligned with the flange 11 of the adjacent opposite wallchannel 3. The glass then is moved inwardly against the flanges 11 ofboth side Walls of the adjusted to project a substantially equal amountwithin each of the gutter members 3. The glass is now raised upward andsetting blocks are inserted to provide vertical support for the glass.It is to be understood that the glass is cut sufficiently larger thanthe sight opening of the window opening so that the adjacent edge of theglass within each gutter member 3 projects inwardly of the gutter memberbeyond the flange 11 as illustrated in Fig. 2 of the drawing.

The glazing operation has now progressed to the point where the faceclips are to be mounted. The face clip of Fig. 3 is shown substantiallydouble size and its actual dimension is about 1 inch long. The guttermember 3 has openings 12a punched in the bottom wall 7 on about 8 inchcenters and the bolts 12 inserted therein. These bolts are usuallyprovided with a knurled shoulder portion which locks the bolt in placein the offset portion 13 of the gutter wall 7 so as to secure the boltsagainst displacement during handling of the sash and rotation duringturning of the nuts 26. Face clips 16 are now mounted on the bolts 12.If the glass is A inch thick the aperture 24 of the clip is insertedover the bolt to bring tongue 27 into engagement with wall projection25a and in so doing the arm 20 is deflected inwardly to obtain apositive resilient contact with glass 2 thereby ensuring resilientlyretaining the glass against sash flange 11. Should the glass be inchthick the face clip 16 is mounted on bolt 12 so as to bring tongue 28 incontact with adjacent projection 25a. Since tongues 27 and 28 are spaced/3 inch apart the clip arm 20 will have the same bearing upon the inchthick glass 2 as previously described for the /4 inch glass. These arethe two popular glass thicknesses and if a greater glass thickness isused special clip 16 must be provided. With the clips 16 thus in place,nuts 26 are applied and tightened to bring the web 17 of the clip intoequal hearing against projections 25 and 25a. In so doing, the webextension 18 of the clip bears against the inner face of gutter memberwall 7 to provide a bearing and pivoting point for resilient arm 19 ofthe clip. After the face clips are applied at the ceiling and side wallor walls the glass is resiliently secured in place and the face membersmay now be applied.

Face members 4 for each gutter member are snapped into position bytilting the web 29 of the member to insert extension 30 past flange 23of the face clip and moving the web 29 towards the gutter member todeflect arm 19 as web extension 32 engages and slides along extension 22of clip arm 19. As the face member comes to rest upon the gutter memberarm 9 or adjacent wall 1, the extension 32 of the face member has movedbeyond offset 22 of clip arm 19 and the arm 19 snaps inwardly beneaththe portion 32 resiliently locking the face member in position. In thislatter position the face member web 29 is resiliently urged against theglass to provide a weather seal at this point. It will be apparent uponreference to Fig. 2 that sufficient clearance is provided between theedge of flange 23 of the face clip and extension 30 of the face memberto permit the face member to engage the glass. Likewise with the facemember in position as described, it is supported upon flange 23 of theface clip and upon the wall surface 1. The face clip preferably overlapsthe adjacent wall surface a sufficient distance to completely close thechannel opening in the wall previously described as being formed toreceive gutter member 3.

Referring now to Fig. 4 of the drawings, wherein is shown a modificationof the sash of Fig. 2, the gutter member 103 is substantially the sameas gutter member 3 except for changes necessary to accommodate the faceclip 116. This latter face clip is approximately the same length andwidth as face clip 16 and is spaced longitudinally of gutter member 103in the same manner, approximately 8 inches on centers. Face clip 116 ispreferably made of resilient material such as spring steel, phosphorbronze or aluminum alloy. The arcuate web 117 of the clip is connectedwith the spaced arms 119 and 120 by substantially arcuate portions asshown. The portion 11712 is so formed as to engage the web 107 of guttermember 103 and fit within the angle formed between web 107 and theinwardly oflset portion 107a of the gutter member. When portion 11712 ofthe face clip is positioned between lug 107a and web 107 of the guttermember face clip portion 117a may be snapped into position by deflectingweb 117 and arm 119 of the clip. By deflecting arm 119 suflicienttension is built up therein to assist in retaining the free end portions121 and 122 in contact with the face member.

To set the clip 116 in place I prefer to press upon the clip portion117a with a screw driver or other convenient tool in the direction ofarrow X. To remove the clip, I prefer to insert the screw driver behindthe clip in the direction of arrow Y and twist. Face clip arm 120 ispreferably formed so as to normally extend towards the glass 2 asindicated by dotted lines so that after the glass is in position withinsash 103 and the clip is mounted, as described, the deflected arm 120bears against the glass with a slight tension to ensure a full bearingbetween clip and glass regardless of the usual commercial tolerances indimensions of the sash 103 and thickness of glass 102.

As previously stated it is preferable, when using recessed sash at theside and ceiling portions of the window opening, to use a conventionalexposed sash at the bottom of the window opening. When this is done, thelarge pane of glass can be readily manipulated in order to mount the topand side edge within the recessed sash.

Throughout this specification and drawings preferred forms of detailconstruction have been illustrated. Many acceptable modifications in allof the various portions of the sash will suggest themselves to thoseskilled in the art while still retaining the invention disclosed herein.It is to be understood that I do not limit myself to the details ofconstruction disclosed except as is made necessary by the scope of theappended claims.
